Marcus D'Amico (born December 4, 1965) is a film, TV and stage actor best known for his role as Michael "Mouse" Tolliver in the original Tales of the Cityminiseries in 1993. He has also appeared in various theater productions. D'Amico was born in Germany to an American father and a British mother, and was brought up in the United Kingdom.

D'Amico did not reprise the role of Michael "Mouse" Tolliver in the 1998 sequel, More Tales of the City, and the role was recast with Paul Hopkins (who also appeared in the third installment, Further Tales of the City in 2001). According to the series' author, Armistead Maupin:

"Despite the rumors, it is not true that Marcus D'Amico wasn't invited back because of issues surrounding his sexuality. The production team met Marcus and he expressed 'ambivalence' about returning to the role of Mouse. The director felt it was important to find someone who would enthusiastically embrace the role."[3]

However, he has referred to his past work on the Tales of the City miniseries as "Exhausting, enlightening and challenging".

When asked about fears of typecasting after appearing in the stageplay Angels in America and in the Tales of the City TV series, D'Amico stated in 2003, "I did get typecast in gay roles but it now no longer worries me."[1]
